A liner rotates a bit to make more hole. The liner has
openings with inserts in them to lend torque resistance to the liner. The
inserts
have a passage with a send control media in the passage and a seal so
that the liner can hold pressure for run in to get proper circulation through
the bit. When sufficient hole is made, the liner is hung off an existing
cemented
tubular and the seal for the passages with the sand control media is
removed by a variety of techniques so that the formation can be produced
in a single trip.
L'invention porte sur une colonne perdue qui fait tourner un trépan pour creuser un trou. La colonne perdue comporte des ouvertures avec des inserts placés à l'intérieur de celles-ci pour fournir une résistance au couple à la colonne perdue. Les inserts présentent un passage avec des agents de contrôle du sable dans le passage et un joint de telle sorte que la colonne perdue peut maintenir une pression pour entraîner la circulation désirée à travers le trépan. Lorsque le trou est suffisant, la colonne perdue est retirée d'un matériel tubulaire cémenté existant et le joint associé aux passages avec les agents de contrôle du sable est retiré par une diversité de techniques de telle sorte que la formation peut être produite en un seul passage.
